Summary: Create a varient of LazyInitializer whch can dispose the
contained object
Key: LANG-1716
URL: https://issues.apache.org/jira/browse/LANG-1716
Project: Commons Lang
Issue Type: New Feature
Components: lang.concurrent.*
Affects Versions: 4.0, 3.x
Reporter: Benjamin Confino
Hello everyone.
Currently there is no clean way to dispose of an object created with a
LazyInitializer. Either you call _initializer.get().dispose();_ but if you've
never used _initializer_ before this will invoke a potentially expensive
routine just so the object can be immediately disposed.
Or you cache the result of _initializer.get();_ and then dispose the object you
have cached. This means the developer has to worry about concurrency issues
when disposing the object, and looses all the benefits of LazyInitializer
having a built in cache.
To fix this I propose that a new variant of LazyInitializer is created, this
variant will allow you to call a dispose method which will close the
LazyInitializer object and then it will, if the wrapped object has been
initialized, run whatever disposal routine is provided.
I have created a pull request with a potential implementation here:
